Specification of Letters Patent.

.Application filed November 8, 1907. Serial No. 401,199.

To all whom it may concern.'

e it known that' l, IHriIP G'. HUBERT, a citizen ofthe United States, residing at Los Angeles, in the county of Los'Angel'es and State of California, have invented new and useful Improvements in Fireless Cookers, of which the following is a specification.

My linvention relates to a tireless cooker in which articles to be cooked may be placed and heated and allowed to remain for a long period of'time without becoming cooled.

The chief object is to provide a cooker in which the articles to be cooked may be initially heated and then removed from the fire while still in the cooker, the articles remaining in the cooker until thoroughly done and it appears when off the fire.

thus obviating the necessity of placing the heated articles. in a cold receptaclekas is the usual operation. 'i

A vfurther vobject is to provide suitable means within `the cooker for cooking or browningthe tops of such articles as puddings, bread and the like.

I accomplish these obj ects by means of the device described herein and illustrated in the accompanying drawings, in which Figure 1,-is an elevation of my cooker as Fig. 2,-is a central vertical section ofthe same taken on line 2-2' of Fig. 1. Fig. 3,-is' a central vertical section similar to Fig. 2, showing the cooker when onthe i'ir'e, Fig. 4,-`-is a view I similar to 3 of a'modified form of cooker for the purposes of baking.

Referring tothe drawings my improved cooker is illustrated as being primarilyv composed of a base 10 and an inverted cup shaped cover 11 which forms the body ortion of the cooker, both cover and base eing suitably insulated so' as to retain .the heat of any article placed therein. Cover 11 may consistof a wooden or thin metal outer casing 12 which may be constructed as shown Ain the drawings of. axnumber of segments secured' together by means of hoops 13 after .the manner of construction of a barrel or tub.

, Within casing 12 and spaced therefrom at a suitabledistance is an inner lining 14 which 1 ispeferably made-of metal and enameled Wit a whitevenamel on its inner surface,l

pan as a lid.

lwhich illustrates the cooker in position on a iire, 16 designates an oil or gas burner of typical construction over which the cooker is placed while the articles therein areheated. A bottoni heating base 17 which fits into cover 11 is adapted to be placed directly above the flame, this heating base having an enlarged or thickened heat conducting portion .18 at its center directly overv the flame. The circularyedge of bas 17 is' turned up to form a conical wedge 19 which isv of such 'a diameter that it will wedge tightly into the bottom opening of the cover as shown in Figs. 2 and 3. Base 17 is provided witha` plurality of radially extending ears or tabs 20 which project outwardly through slots 21 in the lower edge of cover 1 1 and are'then turned upwardly and bent' to form hooks 22. Mount-l' e( on the side of cover 1 1 are a corresponding plurality of catch hooks 23 which are'adapted to engage with hooks 22 and lock the heating base and the `cover tightly together.

(looking rece tacle 24is adapted to be* A placed within t e cooker ul on ase `17 as shown in Figs. 2 and 3. his receptacle 7 may be made of any suitable material but- I referably em lo a receptacle constructed ofpivhite enameledmetal. A lid 25 whose sectional construction is shown in Fig. 2 is also made of metal and is provided in "the center of its upper face with a knob 26 adapted to contact with the top of the inner lining of cover 11, the relative heights of the different parts being arranged so that lid 25 will beheld tightly on receptacle 24 when heating; base 17 is securely in vosition in the bottom?" of the cover; The lic is flanged as at 27 to iit tightly around theupper edge of receptacle 24 so as to hold therein the vapors generated.

ln Fig. 3 vl have illustrated a modified form of receptacle which consists of two separate pans, one abovethe other. When on y one pan is desired to be used the lower one may be utilized and covered by the upper In the use of my improved cooker the articles to be cooked'are placed within .receptacle 24 as at 30, being covered with Water 31 as desired. The receptacle is then placed on heating base 17 and cover 11 is placed over the receptacle and forced down on base 17 until hooks 22 and 2 3 may engage with each other and hold the cover and securelytogether. The whole is then lifted by means of a handle 32 secured to the top.,

Base 1()v is constructedwith an outer casing 13.3 which may be of Wood as illustrated or of sheet metal of suitable'thickness. This casing,v is cup shaped and contains a vheat insulating materia 34 which may b'e mineral wool or similar substalkice.v The center of this material is depressed by a plate of metal 35 which is held down 'by means of screws 36 so that a s ace is afforded for thickened portion 18 of ase 17. Theportions of material- 34 surrounding plate S'are faced lby a sheet of asbestos paper 87 u on which base 17 and cover 11 rest. The as estos paper kee s the insulating material from becoming. soi ed or g displaced and may be ,easily replaced when necessary.4 Cover 11 maybe provided,.if necessary with a plurality of catch'hooks 38, similar' to hooks23, which engage with'eyelets 39 mounted on basel0, thus firmly securing the' cover and base together, but the weight of the cover will generally be found suicient.

'of a cook tove plate.

In' Fig. 4 I have illustrated Ia modified form of cooker which maybe square, rectan ular-or oval 1n plan and which is especia y ada ted for baking purposes. To facilitate't e baking of articles laced therein, such as bread 40 as illustrate ,I haveprovided. a lid 41 which is somewhat .similar in construction to lid 25. Lid 41 is thicker than lid 25, being about the usual thickness A( lifter hole 42 isprovided to acilitate the handlingof the lid as this lid is designed to be heated before being placed in the cooker so that the to ofthe read may bev cooked or browne by the heat radiating thereupon from the lid.

From the foregoing description it Will be noted that I have provided a cooker in which articles to be cooked may-be placed and heated and allowed to remain until thoroughly done. This method ofvprocedure has a great advantageover methods formerly employed in that the heatedarticles do not have to be placed ina-cold cooker after having been ta en from Vthe fire. cooker it is heated to the same temperature to which theA articles therein are heated, so

therein are heated In using my Y that none of theheat frbm the articles to be cooked is transferred to the cooker and thus lost, soy far' as the cooking of the articles concerned..

The prime feature of this invention Will thus be seen to involve a heat insulated cover -in combination With a heating base of heat conducting material and an insulating base upon which the whole is placed when thoroughly heated.

By the construction of the receptacle and the cooker I am enabled to efficiently retain the vapors generated within the same. This is accomplished by means of the lid upon the interior receptacle and also byz means of the formation and placement of the joint between the cover and the basel of the cooker.

This joint is made at the bottom of the cooker so that the hotter part of the vapors which accumulate at the top will not escape should any leakage take place. A joint of suicient size and insulation of rsufficient thickness-may be used to insure the retention of the heat within the cooker for a sufficient length of time tothoroughly. cook any article of'food'. l

` The metal arts of myvcooker may be made of any suita le material, but I preferably employ white enameled metal as it most eHiciently reflects the. heat onto the receptacle and articles therein.

.Having described my invention what I claim as new and desire to secure by Letters Patent istl 1. In a fireless cooker, a heat insulating cover of inverted cup shape, a base plate for said cover, said base plate being provided with a heat conducting portion adapted to be brought into directucontact with heat roducing means, means to attach said ase plate to said cover portion, and a heat insulating base.

2. A fireless cooker comprising, a heat insulated cover of lnverted cup shape, a metallic base plate provided with a heat con-\ ducting portion, a conically formed ring on said base plate adapted to seal the junction l of November, 1907.
